The first one, appeared immediately at the beginning had no effect. The application started to compute and it successfully called a big parallel eigensolver. The second message appeared after 18~19 hours of non-stop computation and the application crashed without showing any other error message! Regularly I was checking that MPI processes were not stuck, after this message the processes were all aborted without dumping anything on stdout/stderr. It is quite weird.

I believe these messages come from Open MPI (but correct me if I am wrong!). I am going to look at the application and the various libraries to find out if something is wrong. In the meanwhile it will be a great help if anyone can clarify the exact meaning of these warning messages.

Many thanks in advance.

Regards,
Filippo
